I make a popular science video and all the emperors learn from it!

【Popular science continues】

【The invention of the wheel is undoubtedly a great progress for mankind. On the basis of the wheel, various transportation tools based on wheels were later developed.】

【The wheelbarrow is perhaps the earliest wheeled vehicle invented by mankind.】

【Its structure is relatively simple and it is so convenient to use that it is not difficult to see it in rural areas today with highly developed civilization.】

【"Traveling on land by car, traveling on water by boat, traveling on mud by sled, traveling on mountains by riding a horse." This is a summary of the performance of several major means of transportation in ancient times.】

【Generally speaking, transportation can be divided into two categories: animal power and human power.】

【Animal-powered vehicles include mule carts, ox carts, donkey carts, sheep carts, carts, donkeys, camels, horses, etc.】

【Human-powered means of transportation include boats, rickshaws, tricycles, sedans, white bridges, shoulders, poles, ice beds, etc.】

【1. Ancient means of transportation】

【The means of transportation in ancient China mainly include boats, mule carts, donkey carts, ox carts, sheep carts, sedan chairs, etc. They are mainly means of transportation that rely on human power and animal power.】

【1. boat or ship】

【Most early humans lived along rivers】

【After working with water a lot, I gradually discovered the buoyancy of water. Some light 340 things will not sink in the water.】

【In order to meet the needs of fishing and crossing rivers, people used simple tools to create the earliest watercraft - canoes.】

【Archaeologists discovered ancient rafts at the Hemudu site, dating back about 7,000 to 5,000 years ago.】

【The history of rafts can be traced back to prehistory】

【The manufacture and application of canoes is a major event in human history】

【Making a canoe was too complicated for primitive people who lacked advanced tools】

【People made improvements by bundling tree trunks, bamboo poles, reeds, etc. into rafts, or using animal skins to make rafts to float on the water.】

【Entering the Bronze Age】

【People have mastered bronze tools and can easily split logs into boards to build wooden boats.】

【With the development of human material civilization, wooden boats and rafts are usually powered by pole oars or oars when sailing, which can no longer meet people's needs.】

【Sail came into being in this situation】

【A sailboat is a boat that uses wind power to move forward. It is an ancient water vehicle after boats and rafts (abaj). It has a history of more than 200 years.】

【According to the number of masts, it can be divided into sloop, ketch and multi-masted sailing ship;】

【According to the ship type, there are flat-bottomed and pointed-bottomed sailboats;】

【According to the bow type, it is divided into broad-head, narrow-head and pointed-head sailboats.】

【The sailing ships used in the Song, Yuan, Ming and Qing dynasties of China include flat-bottomed sand ships, pointed-bottomed Fu ships, Guangzhou ships, fast small boats and bird ships, as well as large warships, building ships and grain-carrying water ships.】

【Sailing boats are usually monohulls, but there are also catamarans that are strong in wind and wave resistance.】

【Sailing boats mainly rely on sails to sail with the help of wind, and rely on oars, oars and poles as means of propulsion, berthing and sailing when there is no wind.】

【2. Car】

【According to legend, during the Xia Dynasty, craftsman Xi Zhong built the world's first real car.】

【Finally, it was further improved and became a horse-drawn carriage.】

【The horse-drawn carriage era that followed for thousands of years】

【There were many types of transportation in the Xia Dynasty, such as"land travel by car, water travel by boat, mud travel by lever""】

【Xi Zhong was named"Che Zheng Dafu" (also known as"Che Zheng") by Xia Wang Yu because of his merits in building chariots."）】

【The emergence of horse-drawn carriages contributed as much as the"Four Great Inventions". Xi Zhong was the earliest and largest inventor and politician in the ancient Xue Kingdom. After his death, he was regarded as the God of Carriage by the people.】

【Later generations built the Xigong Temple at Qianshantou in Xuecheng District to worship him all year round for safe travel.】

【Therefore, there is a local folk proverb of"worship Xi Zhong and travel safely".】

【During the Han Dynasty, the"chicken bus" appeared"】

【The name"Chicken Bus" comes from probably because its shape looks a bit like a chicken bus.】

【A huge wheel stands high, like a high-spirited rooster's comb; the two wings are strong wooden frames for stacking goods; the two wooden handles at the back are lifted up by the pusher and placed next to the hips, naturally like an open tail.】

【""Chicken Bus" is a kind of unicycle with a long history.】

【It is made of hardwood and is 4 meters long. The frame is installed on both sides of the wheel. It is pushed by one person holding the two handlebars. Sometimes it can also be pulled forward and pushed back. It can carry people and objects.】

【Cars were first pushed and pulled by people. 】(To read exciting novels, go to Feilu Novel Network!)

【After people were able to tame cattle, horses and other livestock, they used livestock for traction】

【Animal-drawn vehicles have greater carrying capacity than human-powered vehicles, are also faster and can travel farther. The single-driving two-wheeled vehicle was the earliest form of animal-drawn vehicle, but later it was driven and pulled by two or four horses.】

【The horse driving the car is called a service horse, while the horses pulling the horse on both sides are called stallion horses.】

【Over the course of its long history, horse-drawn carriages have gradually become the most commonly used means of transportation on land.】

【In the war, the carriage also became a powerful weapon. With its speed and strong impact, it became the ace of all arms.】

【Similarly, some smart people began to domesticate animals such as mules, oxen, and donkeys as means of transportation.】

【In the Tang, Song, Yuan, Ming, Qing and other dynasties】

【The decoration of the carriage will vary depending on the aesthetics or actual needs of the people at that time. For example, people in the Ming Dynasty designed the carriage with doors on the left and right or front and rear, making it more convenient for passengers to get on the carriage and making the entire carriage more ventilated, making it a good choice for long-distance business travel.

【At that time, in addition to horse-drawn carriages, there was another means of transportation, which was the sedan chair.】

【It is a means of transportation that relies on human or animal power】

【The power of a tool like a sedan is people, so often only those who are rich and powerful can afford to hire people to lift the sedan.】

【In China, sedan chairs have become a symbol of people’s identity and status.】

【3. Sedan】

【The origin of sedans is unknown, but there are many types, such as official sedans, civilian sedans, wedding sedans, soul sedans, etc., and their spread is very wide.】

【4. Ancient version of bicycle】[]

【According to historical records, during the Kangxi period of the Qing Dynasty, a man named Huang Luzhuang developed China's first bicycle.】

【It has a wheel at the front and rear, and it moves forward through a hand-cranked shaft, but it cannot turn.】

【About a hundred years later, the Frenchman Sifulak invented the wooden bicycle】
